3D Broadband Ground-Motion Simulations of Cascadia Megathrust Earthquakes: Full-Margin Scenarios Incorporating Variable Magnitudes and Frontal Thrust Splay Faulting

Great megathrust earthquakes (∼Mw 8–9) that rupture along the Cascadia Subduction Zone pose significant shaking and tsunami hazards to the U.S. Pacific Northwest. Although these large earthquakes are documented in the geologic record, none have been recorded with modern instrumentation, complicating regional seismic...
